I am sorry, but winny does not take 3-4 weeks to kick in. It's fast acting and you will reap its effects during the latter part of the first week. If you want to end your cycle with a 2 week diet, then I think your best bet would be to add the winny 3 weeks from the end of your cycle instead of two, so you'll get its benefits for the final 2 weeks. If all you have to lose is several pounds of fat, this can easily be done in 2 weeks with proper diet, exercise and little goodies like ephedrine, caffeine, clen (which I personally hate), T3 and DNP. Non aromatiazable androgens like winny will help preserve muscle while dieting, but if your going to use test for the cutting part of your cycle in conjunction with the winny, I suggest using an anti-estrogen such as clonid or better yet arimidex. An anti-aromatase like arimidex will prevent aromatizing activity of test. to estrogen which can hinder fat loss. Good luck.
